【摘要】：目的:探讨实时三维超声心动图(RT-3DE)测量正常新生儿左心室容积及收缩功能的可行性及准确性。方法:回顾性分析我院接受RT-3DE检查的93例正常新生儿,应用3DQ Advance软件测量左室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、每搏量(SV)及左心室射血分数(LVEF)。同时应用二维超声心动图(2DE)双平面Simpson法测量LVEDV、LVESV、SV及LVEF值,并对两者的检测指标结果进行相关性分析。探讨性别、胎龄、出生体质量和心率对各检测指标的影响。结果:RT-3DE所得LVEDV、SV、LVEF均值略大于2DE双平面Simpson法所得均值,且差异具有统计学意义(P0.001);而LVESV均值RT-3DE稍小于2DE(P0.05)。两种方法检测的LVEDV、LVESV、SV及LVEF值之间均具有高度相关性(r=0.94、0.87、0.94和0.75,P均0.001)。性别、胎龄、心率对RT-3DE检测的LVEDV、LVESV、SV及LVEF值均无影响,而出生体质量与LVEDV、LVESV、SV存在正相关关系,对LVEF则无影响。结论 :RT-3DE作为一种无创的、崭新的三维成像技术,能够全面、快速、准确定量正常新生儿左心室容积及收缩功能,具有广泛的临床应用前景。
[Abstract]:Objective: to investigate the feasibility and accuracy of real-time three-dimensional echocardiography in measuring left ventricular volume and systolic function in normal neonates.Methods: the left ventricular end-diastolic volume (LVEF), end-systolic volume (LVESVV) and left ventricular ejection fraction (LVEF) were measured by 3DQ Advance software in 93 normal neonates undergoing RT-3DE examination in our hospital.At the same time, two dimensional echocardiography (2DE) was used to measure the SVSV and LVEF values of LVEDVV and LVESVV, and the correlation analysis was made between the results of two dimensional echocardiography and two plane Simpson.To investigate the influence of sex, gestational age, birth weight and heart rate on the indexes.Results the mean value of LVEF obtained by: RT-3DE was slightly higher than that by 2DE biplane Simpson method, and the difference was statistically significant (P 0.001), while the mean RT-3DE of LVESV was slightly lower than that of 2DEP 0.05.There was a high correlation between the SV and LVEF values of the two methods.Sex, gestational age and heart rate had no effect on the SV and LVEF of LVEDVV, but there was a positive correlation between birth weight and LVEVSVSV, but no effect on LVEF.Conclusion as a noninvasive and brand-new three-dimensional imaging technique, the volume and systolic function of left ventricle in normal neonates can be measured completely, quickly and accurately by using RT-3DE, which has a wide clinical application prospect.
